Apple today released a new update for Safari Technology Preview, the experimental browser Apple first introduced over two years ago in March of 2016. Apple designed the Safari Technology Preview to test features that may be introduced into future release versions of Safari.
The new Safari Technology Preview update is available for both macOS High Sierra and macOS Mojave, the newest version of the Mac operating system that’s currently being beta tested by developers.
The Safari Technology Preview update is available through the Software Update mechanism in the Mac App Store (or in System Preferences in Mojave) to anyone who has downloaded the browser. Full release notes for the update are available on the Safari Technology Preview website.
Apple’s aim with Safari Technology Preview is to gather feedback from developers and users on its browser development process. Safari Technology Preview can run side-by-side with the existing Safari browser and while designed for developers, it does not require a developer account to download.
